Family Scientific Name: Asteraceae
Family Common Name: Sunflower family
Scientific Name: Madia elegans Lindley
Common Name: common madia
Species Code: MAEL
Ecotype: seeds were collected from Lane Co, Oregon near Eugene.
Propagation Goal: seeds
Propagation Method: seed
ProductType: Propagules (seeds, cuttings, poles, etc.)
Time To Grow: 0
Propagule Collection: Seed heads are clipped from plant when the sepals begin to reflex.
Propagule Processing: Seeds were cleaned using a small air screen machine.
Growing Area Preparation/
Annual Practices for Perennial Crops:		 Seeds were sown into cone-tainers filled with Sunshine#1 (a soil-less, peat-based media) amended with micro-nutrients (Micromax) and a slow-release fertilizer (Osmocote 14-14-14). Flats of conetainers were placed in greenhouse set at moderate temperatures (70 degree days/ 50 degree nights)
Establishment Phase: Seeds germinated readily with no treatment. Most seeds germinated within one to two weeks.
Active Growth Phase: Plants grew quickly and when roots had sufficiently filled the cone-tainer (about 1 month), they were transplanted into 5'X6' tub filled with 12" of amended Sunshine #1 mix. Plants were spaced 6" apart and watered as needed. Plants grew to 3' feet high and were covered with blooms.
Length of Active Growth Phase: 4 months
Harvesting, Storage and Shipping: Seeds were collected from individual seed heads when sepals began to dry and reflex. They were dried on tarps in a greenhouse and cleaned in an air-screen machine.
